I got my first pair in Medium and loved them. I did find over time that my platypus feet are a bit swollen at times and simply WIDE, so I contacted Barreletics. They were so helpful and kind. Although I am a 6.5, they thought I might be served well by a size large. AND they offered to send one to me for free - just to be sure I was happy. Boy, am I happy! The fit is much better and the length is forgiving. All of the ladies in my Pilates studio have asked about them. And my yoga class. And I hope to wear them to Barre too. So many uses. So easy to clean. And wowza - all of the colors. I suggested getting a bright fire engine red model as well. This review is long overdue. I have been out of the country but now I am here to tell you all - go out and get a pair if every color. My Pilates holds have never been more secure. You will love them!!!!
